Title: Telephone cable wire tester - uses audio signal for open and short circuit and wire identification and includes impedance bridge
IPC: G01R31/02
Filed: 1978-04-19
Abstract: The telephone cable wire tester uses an audio signal for open and short circuit and wire identification in a cable with two speaking wires in addition to the tested wires. A transmitter (11) contains an impedance bridge consisting of two fixed resistors (R1, R2) and the subscriber terminal (40) connected by the test and speaking wires (Rx, Ra).

Title: Swimming pool roller cover torsional moment check - involves different centres for line between bearing points and roll's centre line
Inventor: TOEDT WOLFGANG
IPC: E04H4/08
Filed: 1978-06-02
Abstract: The system prevents torsional moment involved in unrolling an articulated roller device of the roller shutter type, wound up on a core and held in side bearings, used for covering swimming-pools. One centre (A) of the coil, formed by the straight connecting line between the bearing points (11) is sited outside another center (b) formed by the geometric centre line or gravity line of the coil (12). The core (10) may be previously formed as a curved line between bearing points, pref. comprising two tubes interconnected by a centre piece with radial play allowed. This effectively checks acceleration caused to torsional moment, and uses the same amount of force for rolling up and unrolling.

Title: Speech scrambler for private branch telephone exchange - uses subscriber station code to operate switch, which prevents operator accessing established connection
Inventor: VOGT ALOIS DIPL ING
IPC: H04Q3/62
Filed: 1978-09-13
Abstract: The telephone exchange has speech scrambling system. In this system the signals on the line resemble noise and could be mistaken for such by the operator. Before a conversation via the scrambler starts, a code is sent from the subscriber station and operates a switch. The switch prevents the operator accessing the established connection until that connection has been terminated by the parties to it. (The operator cannot therefore disconnect the connection or listen in).

Title: Solar energy converter - has electret catcher surface with Fresnel lenses over solar cell
Inventor: PRUSS GUENTER
IPC: F24S23/30

Abstract: Fresnel lens formed at ring zones of electret collector in the solar energy converter enhances the efficiency of the unit. The lenses increases the concn. of solar radiation on large catch surfaces of the converter with converter in the focus zone even in the case of diffuse light due to clouded sky. The effect of lenses is shown in the polarisation of electret material and of its pigment molecules ensuring a high absorption of a radiation. THe Fresnel lenses of electret made of acrylic glass holding fluorescent molecules are opposite the solar cell set at a distance which results in uniform irradiation. The cell is set in a guide of the metal housing.

Title: Electric machine intense under-pressure development - uses diffuser terminating with one or two apertures at electric motor
Inventor: BRKIC BLAGO
IPC: H02K9/06
Filed: 1979-12-10
Abstract: To avoid increasing the dimensions of the electric motor through use of an air exhauster wheel of increased diameter to compensate dispensing with a diffuser arrangement, the diffuser is designed and arranged in the assembly to give free air-flow from out of the stator air ducts or from above the stator laminations stack to the air exhauster. Thus, the diffuser(4) terminates with either one or two apertures at the electric motor wall(6), whereby one cover plate is removed from the coil winding head, and the other from the bearing shield sufficiently to allow an axial, enclosed duct to be formed between the electric machine wall(6), the diffuser(4) wall(7) and plate, for air flow from out of the space around the coil winding head up to the space between the bearing shield and the cover plate or the air exhauster(2).
